IMPROVEMENT IN SELF-ACTING SEWER-BASIN TRAPS.

Specification forming part of Letters Patent No. 110,829, dated January10, 1871.

To all whom it may concern:

Be it known that I, MATTHEW K. GOUzENs, of Yonkers, in the county ofWestchester and State of New York, have invented a new and -ImprovedSelf Acting Sewer Basin Trap 5 and I do hereby declare that thefollowing is a full, clear, and exact description thereof,

means for preventing the clogging of pipes which lead from basins orreceptacles to sewers, and for consequently obtaining a constan outletfor such basins.

The invention consists in the application to the end Of the pipe Withineach .basin Of a iioat-valve which is closed as long as the Ordinaryoutlet is open, but will be raised oft its seat to provide anotheroutlet, if the former is clogged.

A in the drawing represents that end of the pipe leading from the basinto the sewer, which is Within the basin. The pipe enters avertical shorttube, B, which is open at both ends, the lower end being but a shortdistance above the ioor of the basin. All liquid matter entering thebasin will rise therein until it enters the lower end of the tube B, andthen escapes through the pipe A.

The uppenend ofthe tube B is closed by a float-valve, C, which is madeof sheet metal, and hollow or otherwise, so as to be lighter than water.It is fitted around avertical rod,

a, which is suspended from a basket-frame, D, iitted upon the upper partof the tube B.

The rod a penetrates the middle of the valve C, and constitutes areliable vertical guide for the same. The upper part of the rod acarries a conical hood, b, which' protects the central opening in thevalve, to prevent dust and dirt from entering and clogging the same.

The basket-frame D protects the valve C against sticks and blocks thatmay be thrown toward it.

Whenever the lower opening of the tube B becomes clogged, the water willrise in the basin until it reaches the valve C, which has a shoulder, c,projectingl over the sides of the tube. The water will oat the valve,and thereby open the upper end of the tube B, so as to provide anotheroutlet to the pipe A. The opening through the middle Of the valve forthe reception of the guide-rod a, I prefer to contract at the upper end,to keep out impurities.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The floating valve C, placed upon the pipe B,which connects With the sewer-pipe, to provide a secondary outlet forthe same, substantially as herein shown and described.

2. The protective basket D, secured to the pipe B, for protecting thevalve C, as specified, and provided with a guide-rod, a, and hood b, forsaid valve, as specied.
